As of Dec. 20, you've voted to abolish the Electoral College, to limit campaign contributions from corporations, to deny corporations the rights of citizens and to prohibit members of Congress from lobbying once they leave office. In our un-scientific sampling, "ratification" required the support of two-thirds of voters. (You can still add your vote here.)

But Christopher Phillips, who has traveled the country sparking discussions about rewriting the Constitution for his book Constitution Cafe, sees loopholes in many of readers' proposed amendments.

He questions whether abolishing the Electoral College, for instance, would actually enable a more diverse set of presidential candidates to run for office — and succeed.

"Or would they still be stymied by the arcane political primary system devised by the two principal political parties to ensure that their candidates will enjoy a vast material advantage in presidential contests, and that were never anticipated by our original framers?" Phillips asks.

While NPR voters wanted to limit campaign contributions, Phillips suggests that the language of the proposed amendment "still seems to leave open the likely prospect that candidates with deep pockets can continue to fund their own campaigns with tens, if not hundreds, of millions of dollars, still making contests far from fair."

On the amendment expressly stating that corporations are not people, Phillips notes that Congress could "continue to show great favoritism when it comes to enacting laws that tremendously benefit corporations to the detriment of small businesses."

"Congress could continue to use its authority to enact bankruptcy laws that bail out the very corporations that were the principal culprits for our current economic morass," Phillips continues.

He notes that, to remedy this, Constitution Cafe participants developed this amendment: "Congress shall have power to enact legislation that treats impartially all the subjects and objects of bankruptcy throughout the United States, and shall have Power to sustain and perpetuate a creditor-debor system of responsibility and accountaiblity. The states shall charter and regulate banks."

And on the NPR reader amendment prohibiting lobbying, Phillips notes that "this language would still permit an ex-member of Congress and immediate family members easily to work around this to their advantage, since it doesn't restrict ex-members of Congress or their immediate family members from doing direct (or indirect) business with the U.S. government as long as they aren't lobbyists or consultants per se."

Here's how all the proposed amendments fared as of Dec. 20:

1. Elections should be conducted in the same way The X Factor takes votes for contestants: by phone, Twitter or email.

10 percent voted to ratify

90 percent voted against ratification

2. The Electoral College should be abolished and presidents should be elected by popular vote.

75 percent voted to ratify

4. Limit Supreme Court seats to a single 9-year term with one seat getting turned over every year. Justices would be chosen by lot from a pool of candidates. The amendment would state the requisite qualifications needed (as decided by both houses of Congress). If you meet the criteria, and you want to be a Supreme Court justice, you enter your name in the pool. The most senior judge is chief justice.

39 percent voted to ratify

60 percent voted against ratification

73 percent voted against ratification
